? for Gord May

Hi Gord,
I have a 36' Prout Catamarn with a 1963 25HP., Izuzu Out-Board 2 stroke oil injected engine. I would like to add a Tachometer and if possible a fuel flow gauge to my panel.
Question is how to do that. The control box has 3 instrument wires 1=Black, 2= Grey, and 3= Yellow. what type of gauge (RPM) would I get and what are the wire location on the gauge?
I'm thinking along the lines of mounting an in-line fuel flow gauge some where before the fuel filter, again what instrument would I use?
Am I just dreaming or is this possible?
Hoping there is an answer to the above questions.

A 1963 Izuzu outboard? Wow, that’s great longevity.

Since gasoline outboards like to run at, or near, wide-open-throttle (WOT), I’m not certain I see much value in a tachometer.
Can I rightly presume that there is nothing presently connected to the (3) aforementioned wires?
I’m not familiar with Izzuzu outboards, so cannot comment on how to add a tachometer - but “Grey” is the current N. American standard colour for Tach’ sender/sensor to display instrument. Check with an Izuzu dealer.

It used to be that fuel flow gauges, such as ‘FloScan’, didn’t work well at consumption rates if less than about 1.5 US Gallons per hour; which I’d hope is less than your 25HP engine consumes. Not certain about some of the newer (and cheaper) units from Lowrance et al. Since most outboards operate from portable day tanks, which are easy to monitor, I’d not be inclined to bother with a remote fuel gauge, never mind a flow meter.

Perhaps others could be more helpful than I ...

Regards,
Gord

Thanks Gord,
I'm inclined to agree with you, but being a former Pilot (Canadian Airforce) I'm partial to gauges.

There’s lots of good (specific & general instrumentation) information on the Teleflex Marine website at: http://www.teleflexmarine.com/
specifically under Instruments & Gauges
and check out the Instrumentation Tech. Ref’ pdf at: http://www.teleflexmarine.com/Pdf/In...TECH%20REF.pdf
Scroll down to pdf to pages 14 through 17 [of 23] (Cat. page 312).
They don’t specifically cite Izuzu, but page 16 shows typical “Japanese” (Honda, Nissan, Suzuki, Tohatsu, & Yanmaha) connections for Yellow, Grey & Black wires.
HTH,
Gord
